Questions & Answers about Он объясняет грамматику правильно и понятно.
What is the grammatical role of the words правильно and понятно in this sentence?
They act as adverbial modifiers that explain the manner in which the verb объясняет is performed. Rather than modifying a noun, they describe how he explains the grammar.
What case is грамматику in, and why is that case used here?
Грамматику is in the accusative case because it is the direct object of the verb объясняет. In Russian, the object that receives the action of a transitive verb is typically in the accusative.
Why are правильно and понятно in their neuter forms, and do they originate from adjectives?
Yes, they come from the adjectives правильный (correct) and понятный (clear). In Russian, when these adjectives are used adverbially to describe how an action is performed, they appear in the neuter short form.
Can the order of правильно and понятно be switched without changing the meaning of the sentence?
